After disabling both items:
1. Left pane - can select files and folders, can open a file, opening a folder causes the program to close
2. Right pane - selecting an item (file or folder) causes the program to close. In one case that I cannot reproduce, a dialog box popped up saying "Index out of bounds".
In all cases, there is a system "ding" that sounds, as if there is an error to present although in all cases except the one mentioned above, no error is shown - followed by several seconds of the "busy" cursor, and then the program closes.
